. BRIQUETTE-FORMING MACHINE.

Application filed September 20, 1924. Serial No. 738,925.

My invention is an improved briquette forming' machine, the prime objectbeing to provide a machine which will quickly and inexpensively formbriquettes from a mixture of carbon, coal dust, oil, and a suitablebinder.

In the annexed drawing vention is illustrated:

Figure 1 is a plan view of my machine.

Figure 2 is a side view of the same with parts broken away to show theinterior construction.

Figure 3 is an end view of the same.

Figure a is an end view of the briquettes forming die.

Figure 5 is a longitudinal sectional view of the piston.

Referring more particularly to the drawing, a crank shaft 1 is journaledin suitable bearings 22 secured to the bed plate 3.

in which my in- The crank shaft 2 has fly wheels t4 secured at eitherend thereof, and is driven from any suitable source of power.

A'connecting rod 5 connects the crank shaft, and a cross head 6. Apitman 7 is secured to the crosshead and to piston 8 whichz extends intoa cylinder 9. This cylinder rests on the bed plate 3, and isprovidedwith an opening 10 in the top thereofover which a'hopper 11 ismounted. This h0pper is preferably bolted to the cylinder 9, orotherwisesuitably attached thereto.

A steam jacket 12 is formed under the cylinder 9 to heat the contentstherein, and I prevent itfrom adhering to the walls. A plate 13 issecured to the forward end of the cylinder 9, and secured to the bedplate 3, and a forming die 1a is mounted in a sleeve 1 1 and has anopening 15 extending there through corresponding to the shape of thefinished briquettes. Pins 14; extend through said sleeve into said dieto hold it in place. An inclined drum 16 is mounted above the hopper 11,and is suitably rotated and fed with the finely divided'substance ofwhich the briquettes are formed, the rotation thereof causing thesubstance to fall into the hopper 11, thence through the opening 10 intothe cylinder 9 in front of the piston 8, the forward stroke of saidpiston driving the charge through the die 14 forming the I I briquetteaccording to the opening in said die.

As the formed briquette protrudes from the end of the die 14, it is cutinto desired lengths in the following manner: A bell crank lever 17 ispivoted to the plate 13 adjacent the die 14, and is formed with acutter" 18 which is adapted to swing over the opening 15 in the die, theother armof said bell crank is connected through a link 19 to one arm ofa bell crank 20 which is pivoted to an armrising from theobed plate 3';the other arm of said bell crank is connected through a rod 21 to aneccentric 22 mounted onthe crank shaft 1. This eccentric is posi tionedopposite to the crank of said crank H shaft thus causing the cutter 18to swing across the opening 15 at the time that the piston 8 is in itsrear position; as the piston advances the cutter swings away from theopening permitting the briquette toprotrude from the die 14 priortobeing cut.

The piston 8 is provided with a pair of sleeves 23 and 2 1, which arepreferably secured thereto by taper pins, and may be removed andreplaced when greatly worn. An

oil pipe 25 extends through thehopper 11 and opening 10 to a pointadjacent the pist'on'8, which lubricates said piston in they cylinderand also prevents the powdered briquette substance from sticking in saidcylinder. v p I I Having described my invention, I claim: A briquetteforming machine comprising a cylinder, a steam jacketbeneath saidcylinder, ahopper opening into said cylinder, a

pipe opening into said cylinder, a piston in said cylinder,renewablesleeves on said pis- I ton, a crank shaft for reciprocatingsaid pie ton, a forming diesecured to the end of said cylinder, a leverpivoted ad]acent said die,

a' cutter on said lever, a bell crank lever pivoted adjacentsaidcylinder, a link connecting said levers, an eccentric mounted on saidcrank shaft, and a rod connecting said eccentric with said bellcrank-lever, whereby the cutter is caused to pass across the outer faceof the die when the piston is in its rear most position. I

In testimony'whereof I afiix mysignature.
